Review of Copadichromis (Teleostei: Cichlidae) with the description of a new genus and six new species

The status of the genus Copadichromis is discussed. Copadichromis prostoma and C. boadzulu are placed in Nyassachromis. Copadichromis cyclicos, C. thinos, C. conophoros, C. flavimanus, C. inornatus, and C. eucinostomus are placed in Mchenga, new genus, diagnosed principally on morphology, bower construction, and habitat preference. In the remaining Copadichromis, three species groups are identified, the C. quadrimaculatus group, the C. mbenjii group, and the C. virginalis group. Six new species are described in the C. mbenjii group: C. melas, C. chizumuluensis, C. diplostigma, C. insularis, C. cyanocephalus, and C. parvus.
